Stainless Steel Shearing Machine Blade

Why Your Stainless Steel Shearing Blades Need Superior Metallurgy？

Why Material Choice Matters for Stainless Steel Shearing？

Key Factors for Success

• Metallurgy Matters: Standard carbon steel blades get dull fast on stainless steel. Our blades use high-quality alloys like Cr12MoV (SKD11) or H13, heated in a deep vacuum to balance toughness and edge retention.

• Hardness vs. Toughness: Harder blades aren’t always better. Too hard, and they chip; too soft, and they get dull. Choose based on the material you’re cutting and how heavy the load is.

• Heat Treatment: Good materials need proper quenching and tempering to work their best. This brings out their wear resistance and toughness.

• Fight Heat and Friction: Cutting stainless steel creates lots of heat. We design our blades to reduce friction, preventing damage to both the blade and the workpiece.

• Prevent Sticking: For sticky materials (stainless steel, titanium alloy, aluminum, copper), use Cr12MoV or SKD11. These blades stop sticking and chipping, making cutting faster and better.

• Precision Gap Settings: Stainless steel needs a tighter blade gap than mild steel. Our blades are made with tiny precision, so you can adjust for burr-free cuts.

• Cost Efficiency: Specialized blades cost more upfront, but they last longer and reduce waste. This saves money in the long run, especially for high-volume work.

Simple Blade Selection Guide (Stainless Steel)

• Light stainless steel / medium strength steel: Choose SKD11 or D2 (balances wear resistance and chipping resistance)

• Stainless steel thick plates / hard-to-shear stainless steel: Choose H13 or LD (handles heavy loads and tough materials)
